I have no idea what your desired output is. I called the Fisher-Yates shuffle subroutine 2x and got this: 
#!/usr/bin/perl 

use strict;
use warnings;
use Data::Dumper;

my @deck = ("A H","2 H","3 H","4 H","5 H","6 H","7 H",
            "8 H","9 H","10 H","J H","Q H","K H",
            "A D","2 D","3 D","4 D","5 D","6 D","7 D",
            "8 D","9 D","10 D","J D","Q D","K D",
            "A C","2 C","3 C","4 C","5 C","6 C","7 C",
            "8 C","9 C","10 C","J C","Q C","K C",
            "A S","2 S","3 S","4 S","5 S","6 S","7 S",
            "8 S","9 S","10 S","J S","Q S","K S");

fisher_yates_shuffle(\@deck);
print Dumper(\@deck);

sub fisher_yates_shuffle { 
    my $deck = shift;
    return unless @$deck;
        
    my $i = @$deck;
    while (--$i) {
        my $j = int rand ($i+1);
        @$deck[$i,$j] = @$deck[$j,$i];
    }
}
